Thanks for your fast reply.
That sounds easy.
And you think that the communication between sensor nodes and Gateway are still possible via wired RS485?
I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?)
For example I like to Switch on/off an light that is connected to an relay board at my sensor node.
Communcation Flow:
OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board
Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library.
During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true?
Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked.
Will the sendMsg method from the MySensor library handle this out of the box?
Regards,
Simon

Hard to say. St:fail generally means that you don't get ack from the receiver. This is normally range, power or hardware. There is not a general fix for this but you need to try and learn... i admit its strange I worked for some days. Maybe a radio fried ?
Don't have the radios to close to eachother. Try a.couple of meters.
Sorry I'm out of more solid ideas.
Hey sundberg84, quick question for you.
If you look at my debug logs above it looks like the gateway is infact receiving the message but the node thinks it fails. Con you confirm my interpretation of the following two lines?
NODE DEBUG
send: 42-42-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=fail:20.0
GATEWAY DEBUG
0;255;3;0;9;read: 42-42-0 s=1,c=1,t=0,pt=7,l=5,sg=0:20.0
If that's correct, could that change what the issue might be?
Yes, I saw that - it seems to work one way but the ack (return) does not reach back. So its on the edge.
But this should update the value in your controller.

Hello,
have you contacted Itead support on this ?
I bought one too but had no time to test it yet (In fact I was waiting for you
No worries, @epierre . I put a test webserver on the iBoard to make sure it was working OK. I was able to browse an SD card over ethernet so I didn't want to bother their support people. I never heard from @nneeoo and just decided to go the hardware route. It seems to be working just fine. I recommend it. It's more stable than the serial gateway I was running.
@canossa Sorry for the late response.
yeah, since is so compact and you can get it for relatively cheap I opted in for the NRF52.
For home automation, I merged MySensors with Domoticz and it works for months now.
